Cancun Express are unreliable and can not be trusted!
We paid Cancun Express for a round trip from Cancun Airport to Playa del Carmen and back. The trip from Cancun was OK. However, there was nobody waiting for us at Playa del Carmen as arranged and paid for in advance. As a result we had to take a taxi which cost us an additional $45.
We have made numerous attempts to contact Cancun-Express but they were all ignored! Their website Cancun-Express.com only allows you to book a shuttle bus, car or van by using Paypal. Paypal has been useless at helping to resolve this so it looks like we are out of $45.
Furthermore, we found that taxis cost the same or less so do yourself a favor and use taxis or another carrier for your transportation needs!
